Si deux et deux sont quatre, Molière n'a pas écrit Dom Juan... by Dominique Labbé Summary

La légende d'un Molière à la fois acteur et écrivain a pris depuis longtemps racine. Ne parle-t-on pas de la langue de Molière ? Il conviendra désormais de dire : langue de... Corneille. En effet, Dominique Labbé démontre, d'une manière aussi méthodique que troublante, que le père des pièces généralement attribuées à la plume de Jean-Baptiste Poquelin est le même que celui du Cid. Comment ? Pourquoi ? C'est l'objet de ce livre clair et courageux. Voici donc un pavé dans la mare culturelle, qui s'attaque à la plus grande icône de la littérature française. Mais pas seulement : c'est aussi une enquête historique foisonnante de révélations, un récit humain captivant et une plongée plus vraie que nature dans la naissance de l'industrie du spectacle moderne. Dominique Labbé est enseignant et chercheur à l'Institut d'études politiques de Grenoble.

Machiavelli’s Prince by Nicola Gardini,Martin McLaughlin Summary

One of the high-points of Italian Renaissance humanism, Machiavelli’s The Prince immediately transcended the time and culture from which it had sprung, circulating throughout Europe and paving the road to an astonishing variety of discussions on power and liberty for centuries to come. Indeed, one could hardly think of a literary work whose reception has been more controversial and arguably more crucial to the fashioning of modernity. This volume gathers together the proceedings of a conference held in Oxford, in November 2013, to mark the 500th anniversary of the composition of The Prince. It explores pivotal aspects of the text’s complex identity, focusing on three interrelated areas: 1. The Prince’s own ways of appropriating ancient and modern traditions of political thought and ethics; 2. the textual history and interpretive details of the work; 3. translations of the treatise into foreign languages (including English and other translations), with their cultural adaptations and reconceptualizations of the original. All chapters offer highly original insights by leading experts on The Prince, shedding light on hitherto neglected topics and locating Machiavelli’s masterpiece in an intriguing network of intersecting perspectives.

Société du parler-français au Canada et la mise en valeur... by Louis Mercier Summary

La Société du parler français au Canada occupe une place prépondérante dans l'histoire des lettres québécoises et plus largement dans celle des lettres canadiennes-françaises. Sa création en 1902 faisait écho aux préoccupations linguistiques d'alors, héritées pour l'essentiel du XIXe siècle. Très vite elle s'est imposée comme l'autorité linguistique et littéraire dominante au Canada français, et elle le demeurera pendant toute la première moitié du XXe. Curieusement, l'ensemble de son oeuvre, l'ampleur et la diversité de ses actions n'avaient fait l'objet d'aucune étude détaillée ; elles méritaient qu'à l'occasion du centenaire de sa fondation un spécialiste vienne en rappeler l'importance. Vouée à l'étude et au perfectionnement de la langue canadienne, la Société est à l'origine de vastes travaux et de nombreuses publications. Mais c'est bien avec son Glossaire (1930) qu'elle a le plus contribué à la mise en valeur du patrimoine québécois. La monographie de Louis Mercier est capitale pour connaître et comprendre les ressources que le Glossaire est en mesure d'apporter à l'histoire et à la recherche. En reconstituant l'histoire complète de l'entreprise, il ne laisse dans l'ombre aucun aspect de la genèse du répertoire. Nous lui sommes redevables d'une analyse méticuleuse et passionnante qui aurait pu être austère mais qui est en fait vivante et chaleureuse. Il a su nous rendre cette aventure presque familière et nous faire partager son admiration pour tous les protagonistes.

Exploring Textual Data by Ludovic Lebart,A. Salem,L. Berry Summary

Researchers in a number of disciplines deal with large text sets requiring both text management and text analysis. Faced with a large amount of textual data collected in marketing surveys, literary investigations, historical archives and documentary data bases, these researchers require assistance with organizing, describing and comparing texts. Exploring Textual Data demonstrates how exploratory multivariate statistical methods such as correspondence analysis and cluster analysis can be used to help investigate, assimilate and evaluate textual data. The main text does not contain any strictly mathematical demonstrations, making it accessible to a large audience. This book is very user-friendly with proofs abstracted in the appendices. Full definitions of concepts, implementations of procedures and rules for reading and interpreting results are fully explored. A succession of examples is intended to allow the reader to appreciate the variety of actual and potential applications and the complementary processing methods. A glossary of terms is provided.

Text Mining with R by Julia Silge,David Robinson Summary

Much of the data available today is unstructured and text-heavy, making it challenging for analysts to apply their usual data wrangling and visualization tools. With this practical book, you’ll explore text-mining techniques with tidytext, a package that authors Julia Silge and David Robinson developed using the tidy principles behind R packages like ggraph and dplyr. You’ll learn how tidytext and other tidy tools in R can make text analysis easier and more effective. The authors demonstrate how treating text as data frames enables you to manipulate, summarize, and visualize characteristics of text. You’ll also learn how to integrate natural language processing (NLP) into effective workflows. Practical code examples and data explorations will help you generate real insights from literature, news, and social media. Learn how to apply the tidy text format to NLP Use sentiment analysis to mine the emotional content of text Identify a document’s most important terms with frequency measurements Explore relationships and connections between words with the ggraph and widyr packages Convert back and forth between R’s tidy and non-tidy text formats Use topic modeling to classify document collections into natural groups Examine case studies that compare Twitter archives, dig into NASA metadata, and analyze thousands of Usenet messages

Common European Framework of Reference for Languages: Learning, Teaching, assessment by Council of Europe Summary

The CEFR Companion volume broadens the scope of language education. It reflects academic and societal developments since the publication of the Common European Framework of Reference for Languages (CEFR) and updates the 2001 version. It owes much to the contributions of members of the language teaching profession across Europe and beyond. This volume contains: ► an explanation of the key aspects of the CEFR for teaching and learning; ► a complete set of updated CEFR descriptors that replaces the 2001 set with: - modality-inclusive and gender-neutral descriptors; - added detail on listening and reading; - a new Pre–A1 level, plus enriched description at A1 and C levels; - a replacement scale for phonological competence; - new scales for mediation, online interaction and plurilingual/pluricultural competence; - new scales for sign language competence; ► a short report on the four-year development, validation and consultation processes. The CEFR Companion volume represents another step in a process of engagement with language education that has been pursued by the Council of Europe since 1971 and which seeks to: ► promote and support the learning and teaching of modern languages; ► enhance intercultural dialogue, and thus mutual understanding, social cohesion and democracy; ► protect linguistic and cultural diversity in Europe; and ► promote the right to quality education for all.

Dès lors, tout traitement infligé aux prisonniers de guerre semble normal en dépit des règles établies par le jus gentium qui finalement ne protège pas le captif. La confrontation des textes et des images livre ici un catalogue éloquent des façons dont les Romains vainqueurs ont pu, abolissant toutes considération d'humanité, exploiter les masses de vaincus ou les révoltés de l'intérieur.

Practical Guide To Principal Component Methods in R by Alboukadel KASSAMBARA Summary

Although there are several good books on principal component methods (PCMs) and related topics, we felt that many of them are either too theoretical or too advanced. This book provides a solid practical guidance to summarize, visualize and interpret the most important information in a large multivariate data sets, using principal component methods in R. The visualization is based on the factoextra R package that we developed for creating easily beautiful ggplot2-based graphs from the output of PCMs. This book contains 4 parts. Part I provides a quick introduction to R and presents the key features of FactoMineR and factoextra. Part II describes classical principal component methods to analyze data sets containing, predominantly, either continuous or categorical variables. These methods include: Principal Component Analysis (PCA, for continuous variables), simple correspondence analysis (CA, for large contingency tables formed by two categorical variables) and Multiple CA (MCA, for a data set with more than 2 categorical variables). In Part III, you'll learn advanced methods for analyzing a data set containing a mix of variables (continuous and categorical) structured or not into groups: Factor Analysis of Mixed Data (FAMD) and Multiple Factor Analysis (MFA). Part IV covers hierarchical clustering on principal components (HCPC), which is useful for performing clustering with a data set containing only categorical variables or with a mixed data of categorical and continuous variables.

The Advanced Theory of Language as Choice and Chance by Gustav Herdan Summary

In trying to give an account of the statistical properties of language, one is faced with the problem of having to find the common thread which would show the many and multifarious forms of language statistic- embodied in scattered papers written by linguists, philosophers, mathe maticians, engineers, each using his own professional idiom - as belong ing to one great whole: quantitative linguistics. This means that the investigator has to find the system of this branch of science which would enable him to arrange the vast material in an orderly fashion, and present it as an organic whole. Such a system is conceived in this book, as comprising the following disciplines as the four main branches of literary statistics: Statistical Linguistics, Stylostatistics, Optimal Systems of Language Structure, and Linguistic Duality (Parts I-IV). The Introduction is meant to define the position of the book with regard to both, linguistics and statistics.

The Book of Why by Judea Pearl,Dana Mackenzie Summary

A Turing Award-winning computer scientist and statistician shows how understanding causality has revolutionized science and will revolutionize artificial intelligence "Correlation is not causation." This mantra, chanted by scientists for more than a century, has led to a virtual prohibition on causal talk. Today, that taboo is dead. The causal revolution, instigated by Judea Pearl and his colleagues, has cut through a century of confusion and established causality -- the study of cause and effect -- on a firm scientific basis. His work explains how we can know easy things, like whether it was rain or a sprinkler that made a sidewalk wet; and how to answer hard questions, like whether a drug cured an illness. Pearl's work enables us to know not just whether one thing causes another: it lets us explore the world that is and the worlds that could have been. It shows us the essence of human thought and key to artificial intelligence. Anyone who wants to understand either needs The Book of Why.

Introduction to Data Science by Rafael A. Irizarry Summary

Introduction to Data Science: Data Analysis and Prediction Algorithms with R introduces concepts and skills that can help you tackle real-world data analysis challenges. It covers concepts from probability, statistical inference, linear regression, and machine learning. It also helps you develop skills such as R programming, data wrangling, data visualization, predictive algorithm building, file organization with UNIX/Linux shell, version control with Git and GitHub, and reproducible document preparation. This book is a textbook for a first course in data science. No previous knowledge of R is necessary, although some experience with programming may be helpful. The book is divided into six parts: R, data visualization, statistics with R, data wrangling, machine learning, and productivity tools. Each part has several chapters meant to be presented as one lecture. The author uses motivating case studies that realistically mimic a data scientist’s experience. He starts by asking specific questions and answers these through data analysis so concepts are learned as a means to answering the questions. Examples of the case studies included are: US murder rates by state, self-reported student heights, trends in world health and economics, the impact of vaccines on infectious disease rates, the financial crisis of 2007-2008, election forecasting, building a baseball team, image processing of hand-written digits, and movie recommendation systems. The statistical concepts used to answer the case study questions are only briefly introduced, so complementing with a probability and statistics textbook is highly recommended for in-depth understanding of these concepts. If you read and understand the chapters and complete the exercises, you will be prepared to learn the more advanced concepts and skills needed to become an expert. A complete solutions manual is available to registered instructors who require the text for a course.

Knowledge Needs and Information Extraction by Nicolas Turenne Summary

This book presents a theory of consciousness which is unique andsustainable in nature, based on physiological andcognitive-linguistic principles controlled by a number ofsocio-psycho-economic factors. In order to anchor this theory,which draws upon various disciplines, the author presents a numberof different theories, all of which have been abundantly studied byscientists from both a theoretical and experimental standpoint,including models of social organization, ego theories, theories ofthe motivational system in psychology, theories of the motivationalsystem in neurosciences, language modeling and computationalmodeling of motivation. The theory presented in this book is based on the hypothesis thatan individual’s main activities are developed byself-motivation, managed as an informational need. This isdescribed in chapters covering self-motivation on a day-to-daybasis, the notion of need, the hypothesis and control of cognitiveself-motivation and a model of self-motivation which associateslanguage and physiology. The subject of knowledge extraction isalso covered, including the impact of self-motivation on writteninformation, non-transversal and transversal text-mining techniquesand the fields of interest of text mining. Contents: 1. Consciousness: an Ancient and Current Topic of Study. 2. Self-motivation on a Daily Basis. 3. The Notion of Need. 4. The Models of Social Organization. 5. Self Theories. 6. Theories of Motivation in Psychology. 7. Theories of Motivation in Neurosciences. 8. Language Modeling. 9. Computational Modeling of Motivation. 10. Hypothesis and Control of Cognitive Self-Motivation. 11. A Model of Self-Motivation which Associates Language andPhysiology. 12. Impact of Self-Motivation on Written Information. 13. Non-Transversal Text Mining Techniques. 14. Transversal Text Mining Techniques. 15. Fields of Interest for Text Mining. About the Authors Nicolas Turenne is a researcher at INRA in the Science andSociety team at the University of Paris-Est Marne la Vallée inFrance. He specializes in knowledge extraction from texts withtheoretical research into relational and stochastic models. Hisresearch topics also concern the sociology of uses, food andenvironmental sciences, and bioinformatics.

A Critical Dictionary of Sociology by Raymond Boudon,Francois Bourricaud Summary

Unlike most other sociology or social science dictionaries, in this translation of the Critical Dictionary of Sociology, taken from the second French edition of the Dictionary and edited by the English sociologist Peter Hamilton, the critical value of this distinctive work is at last made available for a wider audience. Each entry grapples directly with an issue, whether theoretical, epistemological, philosophical, political or empirical, and provides a strong statement of what the authors think about it. The discussions are considered but argumentative. By reaffirming that a non-marxist style of critique is still possible, Boudon and Bourricaud have presented a distinctive approach to the key issues which confront the societies of the Twentieth and Twenty-First centuries. For some this work will be a textbook, for others an indispensable sourcebook of sociological concepts, and for most a way of opening our eyes to new dimensions in our understanding of the great ideas and theories of sociology.

The Grammar of Graphics by Leland Wilkinson Summary

Written for statisticians, computer scientists, geographers, research and applied scientists, and others interested in visualizing data, this book presents a unique foundation for producing almost every quantitative graphic found in scientific journals, newspapers, statistical packages, and data visualization systems. It was designed for a distributed computing environment, with special attention given to conserving computer code and system resources. While the tangible result of this work is a Java production graphics library, the text focuses on the deep structures involved in producing quantitative graphics from data. It investigates the rules that underlie pie charts, bar charts, scatterplots, function plots, maps, mosaics, and radar charts. These rules are abstracted from the work of Bertin, Cleveland, Kosslyn, MacEachren, Pinker, Tufte, Tukey, Tobler, and other theorists of quantitative graphics.

The Dynamics and Challenges of Tetranormalization by Henri Savall,Veronique Zardet Summary

This volume continues the collaboration between the RMC book series and the French management research think tank ISEOR (Socio-Economic Institute for Firms and Organizations). Those familiar with Henri Savall’s and his colleague Véronique Zardet’s earlier work on the socio-economic theory of organizations will recognize their assessments of organizational dysfunctions and hidden costs – but in a different context. In their current work, the emphasis is on the tensions created by the wider environment – the idea of tetranormalization – and how those tensions shape and influence organizational life. Drawing on a wide range of examples from the news media and popular press, Savall and Zardet paint a disturbing picture of the underlying dynamics and challenges posed by a literal avalanche of standards and norms – which are often ambiguous and conflicting – that literally encompasses all that we do. Their analytic framework is composed of four “poles” – two social dimensions and two economic dimensions – that capture social norms and quality, safety and environment standards (the social dimension), and trade-related norms and accounting and financial standards (the economic dimension). Throughout the volume, Savall and Zardet’s analysis captures the myriad ways in which these dimensions interact, shaping the “rules of the game” that dictate how organizations compete and collaborate. Differentiating the “rules of the game” from “playing with” those rules, they delve into the subtleties and nuances that underlie these “poles,” providing further insight into how these forces are manipulated through lobbying and the seemingly 24/7 cycle of exposing, publicizing and rule-making surrounding social and economic as well as scientific and technological controversies. As Savall and Zardet argue, we are in the midst of a profound upheaval that will play havoc with our economic and social lives for some time to come. If we are going to exert influence on that reality, the challenges that we face moving forward must be conceptualized, constructed and implemented today, for, as they argue, “the road to durable prosperity will be a long haul.” Yet, moving beyond these challenges per se, they underscore that we are also presented with an exceptional opportunity – the very real opportunity to create a sustainable commitment to responsible and responsive organizational performance, one that can be fuelled and financed by our ability to translate the hidden costs that exist in all our organizations into productive, value-added activities and true wealth creation. Their analysis presents an intriguing challenge to traditional notions of corporate social responsibility, delving into the idea of “durably acceptable” responsibility, ways to facilitate greater stakeholder engagement, and how we can capture ongoing and sustainable improvement in organizational performance.
